ADJUSTABLE BUTT-HINGE.

SPECIFICATION forming part of Letters Patent No. 310,033, dated December30, 1884'.

Application filed September 15, 15383. (No model!) To all whom, 'L' mayconcern:

Be it known that I, ROBERT G. S. GOLLA- MORE, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ot'Massachusetts, have invented a new and useful Improvement in AdjustableButt-Hinge and Hinge Attachments, of which the following is aspecification.

The object of my invention is to provide an improved means for adjustinga doorl to its jamb or frame and to the sill, in thc event of itsbinding or sagging, after it has been hung and without removing thedoor.

1t is well known that doors after they have been hung will in mostcases, owing to the expansion or contraction of the ja mb or the doorsthemselves, or to the settlement of the walls or frame, bind or sag insuch a way as to render them diflicult to close and also difiicult tolock when the bolt falls a little below its proper place in relationtothe striker.

, In order 'to obviatc this objection and remedy the difliculty, it isnecessary to 'take the doors off and remove a portion of the edge, anop-V eration requiring time and skill and involving expense. Inadjusting a door vertically as now practiced a washer is placed upon thehingeispindle, which also necessitates the 'removal of thc door.

My invention is designed to obviate these diiiiculties; and it consistsof a plate or piece of metal which is to be sunk into and secured to thejamb where the hinges are to be. In this plate or piece of metal is arecess of sufiicient length vertically to admit of the insertion oi' oneofthe leaves of a hinge, but leaving a space between the leaf and theplate. Passing through the plates are screws, upon which the leaf of thehingebears, holes of K smaller diameter than the heads of the screwsbeing made over the screws, so as to enable them to be turned asdesired. By turning the inner screws and at the same time adjusting thehinge-screws the hinge-leaf can be moved toward or away from the frame,and thus adjust the position of the door relatively to the frame. asdesired.

Referring to the accompanying drawings, Figure 1 is a view of an openhinge with my invention attached. Fig. 2 is an end or side elevation ofmy attachment connected to a 1 d ri ver passing through the said holes.

portion ofthe door-frame and to a leaf of the hinge. Fig. 8 isa verticalsection of the hingejoint and spindle on the line x of Fig. 1. Fig; 4 isa side view of the plate attachment, and Fig. 5 is a rear view of thesame.

A B represent the leaves of an ordinary butt-hinge with the joint E E. Cis a metal plate ofthe form sidewis'e as shown in Fig. 4. and is castwith the bosses or projections D on its rear or inner side. These bossesare made hollow, and are screw-threaded. The

plate C, with the bosses D, is sunk into the frame, as shown in Fig. 2,the face of its upper and lower ends being iush with the face oftheframe. A portion of one of the leaves B is fitted within the recess ofthe plate C andA so as to admit of being freely moved between the upperand lower projections, G C, ofthe recess. The portion of the leafB whichis fitted to the plate C bears upon the heads of screws D, the heads ofwhich are of a little larger diameter than the holes in the leaf B, soas to admit of their being turned by a screwlt will thus be seen that byturning the screws D inv or out and correspondingly adjusting the screwsD, which secure the hinge to the doorfraine attachment, the position ofthe door will be relatively adjusted to the frame, as required. Theupper portion of the joint E is attached to or forms a part of the leafA, which is secured to the door, and the lower part, E', is connected tothe leaf B. The two parts are separated a little distance from eachother at the center, as shown in Figs. 1, 2, and 3. rlhe spindle isenlarged at the center F, as shown in Fig. 3, with diminished upper andlower ends iitting, respectively, in the more solid upper and lowerjoints, E E.

In the lower end of the joint E is fitted a screw-plug, G', the upperend, g, of which is diminished and screw-threaded to screw into the moresolid portion of the joint E', and upon the top of the screw-threadedportion g is supported the lower end of the spindle. Provision is madefor turning the screw-plug G by means of a screw-driver, or the outerend may be so constructed as to be turned by a wrench. By turning thescrew-plug G up or down the spindle carrying the upper portion of thehinge, which is attached to the door,

will be correspondingly raised or lowered, and thus allow the door to beadjusted higher or lower, as required.

I do not clainnbroadly, a pintlc-adjlisting` device; but

That l claim as my invention7 and desire to secure by Letters Patent,is-

1. The metal plate O, constructed with the upper and lower projections,C C, and with the hollow screw-threaded bosses D, in conibination withthe leaf of a butt-hinge, B, and provided with attaehing and adjustingscrews, substantially as and for the purpose set forth.

2. The combination of the leaves A B, provided with lthe jointsE E', thespindle F, screw r 5 G, and the recessed plate C, the hollowscrewthreaded bosses D, and screws D', as shown and described.

In testimony whereof I have signed my name to this specification in thepresence of two sub- 2o seribing witnesses.
